Of course the force changes during the impact - so to get close to an answer, you need both the time of the impact and the magnitude of the momentum transfer. As user77567 pointed out, a fairly simple way to measure momentum transfer is with a ballistic pendulum. This would be a heavy steel ball (much heavier than the hammer) hung from a long wire.

A physical pendulum is an object suspended in a uniform gravitational field from a point other than its center of mass. The object can rotate about an axis through the suspension point. When the CM is displaced from its stable equilibrium point under the support, the gravitational force exerts a torque about the support, resulting in angular acceleration.
